Evidencepartial
Across prompts and seeds, encoder cross-attention exhibits a consistent coarse-to-fine spectral progression, yielding a stable time-frequency fingerprint of token competition.
Implicationpartial
Directly stated in the abstract and explicitly confirmed in the analysis section as a key finding.
Verificationpartial
partial
Evidencepartial
Building on this structure, we introduce Attention Frequency Modulation (AFM), a plug-and-play inference-time intervention that edits token-wise pre-softmax cross-attention logits in the Fourier domain.
Implicationpartial
Explicitly defined as the core contribution in the abstract and detailed in the method description.
Verificationpartial
partial
Evidencepartial
low- and high-frequency bands are reweighted with a progress-aligned schedule and can be adaptively gated by token-allocation entropy, before the token softmax.
Implicationpartial
The method is explicitly described with equations and a schedule function.
Verificationpartial
partial
Evidencepartial
Experiments on Stable Diffusion show that AFM reliably redistributes attention spectra and produces substantial visual edits while largely preserving semantic alignment.
Implicationpartial
Claim is directly stated in the abstract as an experimental outcome.
Verificationpartial
partial
Evidencepartial
Finally, we find that entropy mainly acts as an adaptive gain on the same frequency-based edit rather than an independent control axis.
Implicationpartial
Directly stated as a finding in the abstract, suggesting a specific functional role for entropy.
Verificationpartial
partial
Evidencepartial
AFM provides a continuous handle to bias the spatial scale of token-competition patterns without retraining, prompt editing, or parameter updates.
Implicationpartial
Explicitly stated as a key capability and advantage of the method in the abstract.
Verificationpartial
partial
Evidencepartial
Hard binary masks can introduce mild spatial ringing due to sharp spectral boundaries.
Implicationpartial
Directly stated as a technical limitation and consideration in the method details.
Verificationpartial

Evidencepartial
Unless otherwise stated, AFM is applied only to encoder cross-attention
Implicationpartial
Explicitly stated in the experimental setup section, defining the scope of the intervention.
